Abstract

PURPOSE:To control the equipment by the revised mode after the restoration from power failure by using an MF signal from a caller so as to revise the control mode in detecting an incoming call during the detection of power failure. CONSTITUTION:If power failure occurs in the incoming signal standby state and a signal is outputted from a detection circuit 19, a control circuit 4 operates a backup power supply circuit 20 to apply power failure processing. In this state, when the circuit 4 counts a prescribed number of pulses from the detection circuit 7 by external incoming call, the circuit 4 turns on the switch 8 to connect the line and the telephone circuit 9 and controls the address of a voice generating circuit 11 to request an address signal for the operating device after restoration of power failure. Then an address signal from the caller is inputted via the MF signal reception circuit 10 to revise the control mode thereupon. In detecting (19) the power failure restoration, the power supply circuit 20 is stopped to control the device by the revision mode.

FIGS. 2(a) and 2(b) are flowcharts showing the programs stored in the ROM (5), and the operation will be explained below based on these. In addition, if the caller is using a tone phone, press the ``Song'' button, or if the caller is using a pulse ``2'' button, then the caller is using the ``L'' button. The following explanation assumes that an MF signal oscillator is used to send an MF signal to the remote control device (3). First, the line is switched to the remote control device (3) side by the cutter (1), and a start signal is given to the control circuit (4) by the input circuit (12). Set the control mode to all off, and turn on Fl (RAM < which indicates whether there is a power outage or not).
6) and F2 (flag area of RAM (6) indicating whether or not the control mode has been changed successfully) are set to rOJ. In this state (the power outage detection circuit (19) has not detected a power outage), a call signal (16Hz
> is detected by the incoming call detection circuit (7) and converted into a pulse. Here, the ringing signal is sent repeatedly by ringing for 2 seconds and stopping for 1 second, so when the control circuit (4) counts the incoming calls and reads the specified number, the control circuit (4)
) connects the same line and the telephone circuit (9) by turning on the switch circuit (8) εON. At the same time, the control circuit (4) controls the voice address of the voice generating circuit (11), and sends out a response message via the telephone circuit (9) saying, ``I'm not home right now. Please enter your password.'' No. 1a is the midfielder

and set Fl to 'l'. From now on, buffer]
・The nurse standby state is maintained by the power supply circuit (20>) (steps ■, ■). In this state, there is a call signal from the outside, and the control circuit (4) receives the pulse from the incoming call detection circuit (7) in a predetermined manner. After counting the number of times, the control circuit (4) turns on the switch circuit (8) to connect the line and the telephone circuit (9), sends out the same response message as above, and checks the PIN number (step @~O), where F
Since l is 11'', Y/1 is -C, the control circuit (4
) controls the one-voice address of the voice generating circuit (11) and sends out a power outage message via the telephone circuit (9), indicating that the power is still out. All off. If there is no change in the control mode, press number 0, if there is, press number 1. Step [phase], ■) will send out a control/menu message via the telephone circuit (9).Here, The control circuit (4) is '1'
When this signal is inputted via the MF signal transmission circuit (10), control mode change processing is performed.

In other words, please specify the address of the electrical equipment that controls the audio address of the audio generation circuit (11) and turns on after one power outage.Once the change is complete, please enter the address of the electrical device that will be turned on after one power outage. Please press "Narume/
After the power is restored by sending messages through the telephone circuit (9),
Requests the address signal of the electrical equipment to be turned on.

Then, the address signal from the caller is received by the MF (δ force receiver 5).
If input via the circuit (10), the control mode is changed based on it. Then, the change processing is completed, and the control circuit (4) sends the roo signal to the MF signal transmission circuit (10).
If input via
Set it to 1° (steps 8 to [phase]), and control the audio address of the audio generator circuit (11) to set the control mode.
A menu message is sent via the telephone circuit (9). This message is for the above processing, so for example, the control mode after power outage recovery is 1st light on, 2nd rice cooker off...
...If there is no change in the control mode, press number 0, if there is, press number 1. It will be changed to. Here, if the control circuit (4) again inputs a signal of "1" via the MF signal receiving circuit (10), it repeats steps [phase] to [phase] in the same way as above, and receives an MF signal of "0". If input, the switch circuit (8) will be activated and the line and telephone circuit (
9) and return the line to the snow standby state (
Step [phase]) (The above is the remote control process in a power outage state).

In addition, when the power is restored in this state, the power failure detection circuit (19)
When a signal is output from , Fl stops operation of the backup power supply circuit (20) because it is set to ``1.'', and controls each electrical device based on the control mode.Here, Since F2 is set to '1.' (
Since the control mode has been changed), change the control mode to all-off again, set F2 to 10 nos), and return to the arrival standby state (step/b)
(Processing after power outage recovery).
